Thanks for all the replies.
I just remembered that I have an external SCSI CD-ROM drive from my now non-working LCIII. The cable is the same DB25 (i think) connector to the computer.
I would imagine that this would work with the A2000 even though it is Apple branded.
Thing is i have no idea what drivers to use. On my A1200 i use IDE, so IDEfix does the trick but with SCSI i have no idea what software / drivers to use.
